PTFE/PFA Lined Pneumatic Control Valve

ALIS Valves offers PTFE/PFA Lined Pneumatic Control Valves for industrial applications requiring precise flow regulation and resistance to corrosive chemicals. These valves feature a PTFE (polytetrafluoroethylene) or PFA (perfluoroalkoxy alkane) lining that provides a chemically resistant barrier between the process media and the valve body. A pneumatic actuator uses compressed air to adjust the valve opening according to the control signal, enabling automated flow regulation and integration with industrial process control systems. The lining and internal components are selected according to the chemical compatibility, pressure and temperature requirements of the application.

PTFE/PFA Lined Pneumatic Control Valves are suitable for applications in chemical processing plants, pharmaceutical manufacturing, acid handling systems, water treatment facilities and other industries involving corrosive fluids. They can be used to regulate compatible acids, alkalis and chemical solutions within the specified operating limits. Important selection factors include chemical compatibility, operating pressure, temperature, flow rate, pressure drop, valve size, lining material, diaphragm or packing materials, pneumatic actuator requirements and control signal specifications. Selecting the appropriate valve configuration helps support accurate flow control, corrosion resistance and reliable automated operation under the intended working conditions.
